Example Spectra The MSP1000 is capable of acquiring high resolution spectra of many different targets. Figure 1 shows some example spectra, acquired using the standard spectrometer configuration (600 lpm grating) with a 25 µm fibre. The solar spectrum was acquired using an MSP1000 with a windowless detector, showing the characteristic blackbody curve and clear Fraunhofer absorption lines. Figure 1. Example spectra as individually labelled obtained using the MSP1000 in standard configuration Software The MSP1000 is supplied with easy-to-use software for acquiring spectra and performing...

Detector Spectral Response The MSP1000 uses a Toshiba TCD1304 linear array CCD detector. The spectral response of this sensor is shown in Figure 3 below. Note that performance below 400 nm will be degraded due to both the quantum efficiency (QE) of the detector and the attenuation of standard optical fibres (which are specified between 400-2200 nm). On request, we can supply the MSP1000 with a UV-coated, windowless, detector which improves the sensitivity down to 150 nm if a suitable fibre is used. Figure 3.

* Standard range, can be modified on request † < 400nm if using a UV coated detector The grating angle determines spectral range; for the standard MSP1000, a 600lpm grating is used and set to give a range of between 400-850 nm. The MSP1000 is a fibrecoupled spectrometer, so spectral resolution is dependent on both the combination of grating and fibre core size. A slit is not required (the effective slit width is the fibre core diameter). The blaze angle represents where the diffraction grating efficiency is highest, so for a NIR applications, a 1000 nm blaze is more appropriate than 500 nm....

Calibration Each MSP1000 is wavelength-calibrated against a Mercury-Argon line source. The calibration coefficients are stored on the device and can be updated via the control software if required. We do not perform a radiometric calibration as this would only be valid for a fixed experimental setup. If you wish to make absolute intensity measurements, you should use a calibrated broadband light source (e.g. tungsten halogen lamp) to obtain the radiometric correction for your spectrometer on a perexperiment basis. Optional Accessories (please enquire) Accessory Compatible WiFi dongle...

Mechanical Drawings Figure 6. MSP1000 Mechanical drawing. All dimensions are given in millimetres. Rubberised feet are attached to each unit for stability on bench surfaces. This adds around 5mm to the height. If you do not wish the feet to be attached, please specify before ordering.
